To check if your ISP is using CGN you need to connect a PC to the router at Radio QTH. or any similar page which will show from which public IP address your request is coming.

How does nat work in an external network?

NAT in the context you describe (i.a. one external and multiple internal IP addresses) works by rewriting the source IP and port of an outgoing connection and adding a state so that replies to this rewritten connection can be mapped back in order to rewrite destination IP and port for incoming packets.

How does symmetric NAT work in a network?

Symmetric NAT. Each request from the same internal IP address and port to a specific destination IP address and port is mapped to a unique external source IP address and port; if the same internal host sends a packet even with the same source address and port but to a different destination, a different mapping is used.

What does it mean when Nessus scans ports?

So for scanning, this means that if the Nessus scan targets the public NAT IP address (or addresses), the ports which are being forwarded to internal servers will be scanned. Devices which maintain NAT translation rules in addition to moving network traffic may experience a CPU/memory hit when processing scans.
